About Us

We specialize in protecting commercial and residential customers with the latest products and technologies in the security and alarm system industry.

And we do it better than anyone else.

Since we began in 1984, Associated Technical Services has provided every customer with quality workmanship, outstanding service, and innovative solutions. Our founders, David and Charles Janzer, have taken the extra steps necessary to ensure complete customer satisfaction … and today, ATS has grown to become southeastern Wisconsin’s premier sound and security systems integrator.

In June 2016, Alarm Systems, Inc. of Quincy Illinois acquired ATS. This union brings even more expertise and capabilities to our Wisconsin customers. Alarm Systems has been recognized as a Platinum Certified Integrator which is Honeywell’s highest level of certification. Platinum certification acknowledges an integrator’s dedication to investing in training and certification of Honeywell products and services for its sales staff, engineers and technicians. It is a distinction reserved for security integrators that demonstrate the highest level of expertise and commitment in Honeywell’s enterprise level systems and products.

Professional. Knowledgeable. Efficient.

Customer Care & Support

If you ever have a question or concern about your home’s security, our customer service representatives are always just a phone call away. It’s our goal to answer your questions or solve your problem with one call.

Our service doesn’t stop there either. Several times a year, we call to test the security system and verify your information. Periodic tests are the best way to ensure your security system is protecting you properly.

Quality Equipment

Protect your home and business with the best home security equipment on the market. Our user friendly security devices make securing your home easy and efficient.

Best of all, we provide all of our customers with hands-on training so they know exactly how to use their equipment and their features. Take total control over your home or business with reliable technology you can trust.

Local Monitoring

In the event an alarm is triggered, you can count on a quick and helpful response from Alarm Systems, Inc.’s local monitoring station. It is a UL listed facility and exceeds all national standards.

In just a few seconds after your alarm is sounded, an alarm operator will pick up the signal and establish a direct communication link with your home or business to ask for identification. They can tell what kind of alarm has been triggered and dispatch the appropriate responders to your home. You can always count on real help when you need it most.

Installation You Can Trust

All security systems are installed by an experienced technician. During the installation, our technicians will treat your home with the utmost respect and care. And of course, we clean up when we’re done.

ASI does not outsource or use subcontractors. When an ASI vehicle pulls up to your home, you’re receiving service from a full-time employee. This ensures that you receive the quality you deserve and the personalized protection you need.
